Abstract

The results of the first experiments with test samples, tool steel and polycrystalline Sn carried out with the scanning photoemission microscope built on the ELETTRA storage ring in Trieste are presented and discussed. The scanning photoemission microscope uses a zone plate optical system for demagnification of the photon beam to submicron dimensions. The present performance of the microscope in photoemission allows elemental and chemical mapping and small-spot photoelectron spectroscopy with lateral resolution better than 200 nm. The reported results show how photoemission microscopy can distinguish the spatial distribution of carbide phases with different Fe content at the surface of a tool steel and the correlation between inhomogeneous oxidation of a polycrystalline Sn sample and its grain structure.

Electron microscope

An electron microscope is a microscope that uses a beam of electrons as a source of illumination. They use electron optics that are analogous to the glass lenses of an optical light microscope. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light, electron microscopes have a higher resolution of about 0.1 nm, which compares to about 200 nm for light microscopes.

Transmission electron microscopy

Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device.

X-ray photoelectron spectroscopy

X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique based on the photoelectric effect that can identify the elements that exist within a material (elemental composition) or are covering its surface, as well as their chemical state, and the overall electronic structure and density of the electronic states in the material. XPS is a powerful measurement technique because it not only shows what elements are present, but also what other elements they are bonded to.
